General Outdoor WiFi MIMO Wireless AP-WDS Backhaul System Structure

1. AP-WDS is working as AP & AP Client, it is specially extended surf internet backhaul, but the throughput will cut down1/2 in the backhaul

because the devices need to transmit AP-throughput and AP Client-throughput, the total throughput will be shared.

2. AP-WDS will have more CPU & RAM …management loading, if the outdoor wireless device CPU & RAM…cannot support enough effect,

the throughput will reduce more and faster.


General Outdoor WiFi MIMO Wireless Repeater Backhaul System Structure

1. Repeater is working as forward transmit, it is specially extended backhaul, but the throughput will reduce 1/2 throughput at each repeater in

the backhaul. Even you set up dual radio for wireless repeater system, the throughput will reduce more and faster.

2. When the latency or act time or reduce throughput situation have happens, this wireless system will meet backhaul dead end problem.

Outdoor WiFi MIMO Wireless Multiple Hops Backhaul System Design Case Studies

Case Study 1: City Wide Road Crossroads High Throughput MIMO WiFi Wireless Surveillance System

Wireless systems design guide: 1. design of multiple hops relay platform to not more than 6 jumped 2.The basis for the design, each wireless

backbone links to no bandwidth over 60Mbps for design requirements 3. In the erection of three forks or crossroads, 103R three wireless

module designs, reserved engineering change link direction to set up or increase future links to expand or equipment upgrade needs.




Design 4 Backhaul to provide 4 * 110Mbps = 440Mbps Throughput for Wireless Surveillance System

Wireless bandwidth prediction commentary: 1. the multiple hops relay platform technology, 1th hop 140~160Mbps, 2nd hops 130~150Mbps,

3rd hops 120~140Mbps, 4th hops 110~130Mbps, 5th hops after to maintain 110~120Mbps bandwidth, lower bandwidth will not increase the

number of platform and response time not less than 10ms.

1. Wireless backbone links for a total of at least 110*4 = 440Mbps available transmission bandwidth 2. Centre for wireless monitoring and management backbone to the intersection near the pool (nearly ends short distance optical networks, if necessary) 3. Minor roads as the backbone for wireless transmission, avoid main roads of trees blocking signal tree failure (Per 1 meter thickness of leaves of street trees decaying 8~15dBm, wireless signal cannot be penetrated ' will be absorbed)

The upper level Multiple Hops: 30Km Throughput 480Mbps for IP Camera * 100 about 300Mbps bandwidth requirement。

System Planning Guide:

1. Multiple Hops each repeater hop, about 5~8Mbps bandwidth reduction, after the fifth repeater hops, the bandwidth will keep on 120~140Mbps, no longer

reduces bandwidth.

2.Upper formation backbone the end each link must withstand 30+30+30+30+30=150Mbps to collect the total bandwidth, the load is very heavy, suggested

that the IP Camera bandwidth setup 2Mbps, Speed Dome setup 3Mbps is suitable, which will bring together reduce total bandwidth to 115Mbps.

3. Wireless by straight line transmission primarily, if the highway has the curve area, must additionally build a repeater hop spot in the curve area, or increase

or decrease adjustments to two points apart.
